This Borehole Inspection Camera  adopts reflective axicon lens to take 360° hole wall images, image acquisition and processing by means of computer to form a continuous hole wall developed image. The hole wall image are developed following the order N→E→S→W→N. The longitude connection of images are jointed as per the order of depth, thus the overall hole-wall image is fully understand at a glance.

Data Processing Function
· Browsing, real-time display of position and depth
· Marking of images and literal texts
· Making of interpretation lines on images
· For convolution rotation, see coregraph
· Calculate the inclination of stratum construction
· Measure the thickness of rock stratum and the width of cracks
